Bond albedo
The bolometric Bond albedo is the quantity required for estimates of thermal inertia and models of the Yarkovsky effect for OSIRIS-REx for Asteroid Bennu. It is generally assumed that the spherical Bond albedo in the V passband (∼550 nm) is a good representation of the bolometric Bond albedo. This is because most of the Sun’s energy …The connection to the Bond albedo anomalies would simply be , and this would be the connection to the CERES Bond albedo if earthshine and CERES observations covered the same parts of the Earth (ignoring differences in data collection and analyses, like the clipping done for earthshine).
